Querying a Cluster List

Function

This API is used to query a list of clusters created by a user. This API is incompatible with Sahara.

URI

  • Format

    GET /v1.1/{project_id}/cluster_infos?pageSize={page_size}&currentPage={current_page}&clusterState={cluster_state}&tags={tags}

  • Parameter description
    Table 1 URI parameter description

    Parameter

    Mandatory

    Description

    project_id

    Yes

    Project ID. For details on how to obtain the project ID, see Obtaining a Project ID.

    pageSize

    No

    Maximum number of clusters displayed on a page

    Value range: 1 to 2147483646

    currentPage

    No

    Current page number

    clusterState

    No

    You can query a cluster list by cluster status.

    • starting: Query a list of clusters that are being started.
    • running: Query a list of running clusters.
    • terminated: Query a list of terminated clusters.
    • failed: Query a list of failed clusters.
    • abnormal: Query a list of abnormal clusters.
    • terminating: Query a list of clusters that are being terminated.
    • frozen: Query a list of frozen clusters.
    • scaling-out: Query a list of clusters that are being scaled out.
    • scaling-in: Query a list of clusters that are being scaled in.

    tags

    No

    You can search for a cluster by its tag. If you specify multiple tags, the relationship between them is AND.

    • The format of the tags parameter is tags=k1*v1,k2*v2,k3*v3.
    • When the values of some tags are null, the format is tags=k1,k2,k3*v3.

Request

None.
